I get a vibration also, but its not the engine. When the drawer is open on the center console (the one where the USB ports are), I'll get a vibration. If I push on the door or close it, it stops. By the sounds of it, I don't believe its the same as what you guys are experiencing, but figured it was worth mentioning.

Vacuum pump? refilling the vacuum reservoir? That is if you have a 6.7.
